AASU chief advisor Samujjal Bhattacharya and general secretary Lurinjyoti Gogoi were taken into police custody on Monday along with more than a hundred protesters during a rally in Guwahati against the citizenship law, officials said.
The AASU's three-day 'Satyagraha' began in the morning and the leaders addressed the protestors at the Latasil playground before beginning a march towards the deputy commissioner's office.
"We have information that we might be arrested but we want to make it clear that our demand is withdraw CAA or arrest us," Bhattacharya said in his address to the protesters.
He urged the protesters to "march in pairs and be disciplined as our protest is non-violent".
The protesters were taken into custody when their protest rally reached near the Dighalipukhuri area, the officials said.
The protesters have been kept at a temporary jail created in a field near Dighalipukhuri where they continued to shout slogans demanding revocation of the Act, they said.
